Plain-English summary
A group of 10 dogs was diagnosed with a nerve-sheath tumor, which caused problems with the trigeminal nerve, leading to muscle wasting on one side of their face. All the dogs showed signs of muscle atrophy in the temporalis and masseter muscles. While some dogs were treated with surgery to remove the tumor, others did not receive treatment and unfortunately had a shorter lifespan, living between five to 21 months. One dog that had surgery is still doing well and has not shown any signs of disease progression 27 months later.

Abstract
Nerve-sheath tumor was diagnosed in 10 dogs with clinical signs of unilateral trigeminal nerve dysfunction. Unilateral temporalis and masseter muscle atrophy were present in all cases. An enlarged foramen and distorted rostral petrous temporal bone were seen with computed tomography imaging in one case. Magnetic resonance imaging was used to identify the lesion accurately in seven cases. Surgery was performed for biopsy and lesion removal in three cases. Cases not treated had a progressive course eventually resulting in euthanasia or death. Of the cases treated surgically, one case is alive without disease progression 27 months after surgery. Survival times of the nontreated cases ranged from five to 21 months.
